What are some good mastering vst's ?

[Theleak]

That work good with FL.

 

[Slum Shaman]

iZotope Ozone. RTFM first, it can be a bit intimidating at first sight, but it's quite powerful.

 

[Alejandro Beats]

I prefer T-racks its so easy to get a quality mix.

 

[BeatGenerals]

I agree with Ozone, although I prefer to use it outside of FL studio in something like Audition.

 

[dogbo415]

ozone 5 (advanced if you can) hands down.. my opinion

 

[Xabiton]

I use T-Racks

 

[City Beats]

I like to mix and match plugins rather than using one plugin suite like Ozone ... I'll use a combination of Waves and Sonnox plugins... sometimes I use Ozone though.

 

[anaujiram]

ozone 5 advanced for sure

 

[Griffin Avid]

I like the ozone option too. So many uses and applications and it's very forgiving if you don't know what you're doing.
Deep, but well laid out.
